To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
A
CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the wrong
kind of extension cord could overheat and
cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt AC outlet. If the cord won't reach, use a
heavy-duty three-prong extension cord rated for
at least 15 amps.
4. Before starting the engine, be sure to unplug
and store
the
cord as it was before
to
keep it away
f r o m moving engine parts. If you don't, it could
be damaged.
How
long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have,
and
some other things. Instead of
,
trying to list everything here, we ask that you contact
your dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice
for
that
particular area.
